Hi everyone,I’m running into an error when a user completes a user task in a workflow. Whenever a user selects an outcome on a user task and continues to the next task, the application throws an error related to Workflow Commons TimelineViewer, even though the workflow itself continues correctly.This initially happened only on the last user task, but it has since started happening on every user task transition.Observed BehaviorAs soon as the user selects an outcome and clicks Continue:The next user task is created and assigned correctlyThe workflow progresses as expectedHowever, an error is logged and shown to the userSo functionally everything works, but the error is still thrown during the transition.Changing member 'WorkflowCommons.TimelineViewer_Workflow' of 'WorkflowCommons.TimelineViewer' by user Inputter failed for security reasons: Setting the value [MendixIdentifier:: id=24488322974071333 objectType=System.Workflow] for reference System.Workflow failed, because the object could not be found or accessed. The exception is a:MemberAccessDeniedException The user can read and edit all fields on the context entity and the application userrole in question has been assigned the WorkflowCommons.User module roleAny insight, explanation, or suggested fix would be greatly appreciated.Thanks in advance!
